EDWARD SPAIN, OF PHILADELPHIA, PENNSYLVANIA.

CHURN.

Specification of Letters Patent No. 5,585, dated May 16, 1848.

To all whom it may concern:

Be it known that I, EDWARD SPAIN, of the city and county of Philadelphiaand State of Pennsylvania, have invented a new and ImprovedBarrel-Churn; and I do hereby declare the following to be a full, clear,and exact description of the construction and operation of the same,reference being had to the accompanying drawings, making a part of thisspecification, in which Figure 1, is a perspective view; Fig. 2, alongitudinal vertical section; and Fig. 3, a perspective view of thedasher of the churn detached.

The nature of my invention consists in giving such a peculiar formationto the exterior surface of the dasher, that it can be placed whole,within the churn, or removed from the same, through a square aperture inthe side, near one end of the churn; the peculiar form of the dasheralso, imparting as it is operated, a compound reciprocating and rotarymotion to the cream, thereby more thoroughly and effectually agitatingthe same, and preventing the cream when it becomes thick, from revolvingwith the dasher.

Similar letters indicate corresponding parts in all the figures.

A, is the barrel of the churn.

B, is the metallic lining and support to the aperture for the receptionof the dasher. The support B, is composed of sheet metal; its lower edgeis turned under the ends and sides of the staves surrounding theaperture, and is secured to the same; and its upper edge is stiffenedand supported by a strong wire, by which means the perfect contour ofthe churn about the aperture, is preserved.

C, is a cover shutting into, and perfectly fitting the aperture supportB.

i, is a tube inserted through, and rising above the cover C, for thepurpose of allowing the gas to escape from the churn, and permittingfresh air to enter the same. The dasher is composed of four beatingwings D, D, D, D, united to two long, and two short, transverse bars E,E, E, E: the ends of the dasher are composed of a long and a short barunited right angularly at their centers; making four radial arms, twolong, and two short. The beating wings are broader at one end than atthe other, and are curved and rounded off, as represented in Fig. 2. Thebroad ends of the beating wings are united to the long arms, and theirnarrow ends to the short arms thus bringing the long arms at one end ofthe dasher, opposite to the short arms at the other end of the same, asrepresented in Figs. 2, and 3.

j, is a bearing box secured to one end of the barrel A, for receivingthe pivot 70, on one end of the dasher.

g is a nut secured to the end of the dasher opposite to the pivot f, isa bearing tube secured in the center of the barrel head opposite to thebearing box 7'. The axle h, of the operating crank G, passes through thetube f, and is screwed into the nut g. The dasher is removed from thechurn by unscrewing the operating axle from the same, and elevating thedasher on to its pivot end by passing the broad ends of the beatingwings at its opposite end, diagonally into the square aperture in thebarrel; when it can readily be lifted out.

The operation of the dashers on the cream is as follows: The alternatingaction of the broad ends of the beating wings at each end of the dasher,imparts to the cream a reciprocating motion from end to end of thechurn, combined with the rotary motion; thereby thoroughly acting uponevery part of the same, preventing the cream, when it becomes thick,from revolving with the dasher, and greatly reducing the time and laborusually required in the production of butter. After churning, the dasheris removed to be cleaned, and the churn is then clear of all impedimentin he way of re moving the butter, and of giving the churn a thoroughcleaning.

Having thus fully'described the construction and operation of myimproved barrel churn; what I claim therein as new and desire to secureby Letters Patent is The giving the dasher the form herein representedand described, which, while it imparts, a compound reciprocating androtating motion to the cream as it is operated. upon thereby, alsoenables a large sized dasher to be passed whole through a comparativelysmall sized square aperture in the side of the barrel, as herein setforth.

EDWARD SPAIN.
